LibJS: Export symbols causing linker errors in various consumers After LibJS had its symbol exports optimized the targets js, test-js, test262-runner, test-wasm, and LibWeb began to get linker errors after the work to add Windows support for test-web and ladybird targets. These extra JS_API annotations fix all those linker errors.

LibJS+LibWeb: Add JS::Object::inherits(class_name) To allow implementing the DOM class hierarchy in JS bindings, this patch adds an inherits() function that can be used to ask an Object if it inherits from a specific C++ class (by name). The necessary overrides are baked into each Object subclass by the new JS_OBJECT macro, which works similarly to C_OBJECT in LibCore. Thanks to @Dexesttp for suggesting this approach. :^)

LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibJS: Begin implementing console.dir The intent of the spec is that the output of console.dir is interactable within the console. Our Printer implementation currently just prints the provided object as a string, and doesn't check the provided `options` argument. But having console.dir defined prevents exceptions from being thrown on real websites.

LibJS+WebContent+Browser+js: Implement console.group() methods This implements: - console.group() - console.groupCollapsed() - console.groupEnd() In the Browser, we use `<details>` for the groups, which is not actually implemented yet, so groups are always open. In the REPL, groups are non-interactive, but still indent any output. This looks weird since the console prompt and return values remain on the far left, but this matches what Node does so it's probably fine. :^) I expect `console.group()` is not used much outside of browsers.
